In 2015, Jisu went to the SHINee concert for the first time. 

The experience was one of the most thrilling moments of her life.

 I heard a song called 'View' then.

In 2016, Ji-Su went to an idol concert called Seventeen. 

It was the second concert she went to.

 I heard a song called 'Very Nice' then.

She stood in the front row and looked them with enthusiasm.

She also attended their fan meetings that year and the following year and shook the cheering sticks hard.

After she entered high school, she went to an idol performance called NCT in 2017. 

I heard a song called 'Touch' then.

She quickly took a taxi to the concert hall as soon as school was over. This experience made me most excited.
